Uroflowmetry is non-invasive and easily performed to diagnose benign prostatic hypertrophy(BPH) frequent in aged men. Weight change during urination is usually measured to estimate the urinary flow rate by a load cell, but sensitive to any impacts against the bottom of the container, leading to unnecessary noise generation. Moreover, load cells are relatively expensive raising the production cost. The present study proposed a new technique, measuring hydraulic pressure on the bottom of the urine container to evaluate the urinary volume. Low cost pressure transducer enabled almost perfectly linear relationship between the urine volume and the hydraulic pressure. During both the simulated and human urination experiments, variance of the pressure signal was more than 50% smaller than the weight signal acquired by a load cell, which demonstrated that the impact noise was decreased to a great degree by pressure compared to weight measurement.

Purpose: This study was to develop an online 'alternative therapy and health promotion' class for university students and to evaluate its changes. Method: The online class was developed based on the Instructional Systems Development(ISD) model and model of Web-Based Instruction(WBI) developmental process. This was a quasi-experimental, one group pretest-posttest design. The subjects of this study were 130 students in 3 universities, and they were provided the cyber class for 16 weeks. Data was analyzed by descriptive and plural answer statistics, and paired t-test. Results: The cyber class was developed in five steps : analysis, design, data collection and reconstruction, programing and publishing, and evaluation. The results of program evaluation were positive, which included learning 3.47. system 3.57, and learning satisfaction 3.64 on the scale of 5. The posttest scores of cognition and reliability of alternative therapy were higher than pretest scores. The posttest score of health promoting lifestyle(t=-5.051, p=.000) and perceived health status(t=2.979, p=.003) were significantly higher than those of the pretest. Conclusion: These results suggest that the cyber class is a positive method in increasing a cognition, reliability of alternative therapy, and is effective to improve a health promotion lifestyle and perceived health status for the university students.

Purpose: This ethnography was performed to explore patterns and meanings of healthy life among aged women using senior centers. Methods: The informants were 21 individuals aged 65 years and older at 2 community-based senior centers. Data were collected from iterative fieldwork through in-depth interviews and participant observations and analyzed using text analysis and taxonomic methods developed by Spradley. Field notes were used with follow-up interviews and dialogue between authors to enhance interpretation. Results: Patterns of healthy life among aged women using senior centers were categorized by age groups within the context of the four cultural elements of taking care of the body, relationality, temporality, and spatiality: active and passive control, maintenance of interdependence and individuality, expansion and maintenance of the daily routine, unity of peer relations and sustenance of family relations, spending time productively and tediously, and complementary and alternative space of the family relations. Conclusion: The informants in this study demonstrated healthy life by maintaining and strengthening continuous relationships developed in the senior centers without being isolated from the family and society. Patterns of their healthy life differed across age groups within the socio-cultural context. Therefore, interventions should be tailored to address age groups and community needs.

This study found a relationship between the characteristics of the elderly with disabilities and extra health care monthly costs caused by disability and suggests methods for effectively managing health care spending of the elderly with disabilities. This study used data from the 2011 Survey on the Disabled conducted by the Ministry of Health and Welfare and the Korea Institute for Health and Social Affairs. The results of the analysis indicate that the relations between the socio-demographic characteristics of the elderly with disabilities and extra health care monthly costs caused by disability of the elderly are influenced by factors such as gender, age, members of the household, average monthly income and type of health insurance. Elderly people with disabilities spend too much for their medical care. To solve this problem, the government needs to find a variety of policy approaches to improve administrative procedure, establish a medical delivery system and enhance health care services.
